ABSTRACT:
Prior-art telecommunication systems include transceiver arrangements structured, for example, as optocouplers for optically transmitting information, that is in a DC isolated manner. These optocouplers, which may transfer relatively high frequency signals are expensive. When the signal, to be transmitted has a low maximum frequency of about 200 Hz, a more cost-effective transceiver arrangement may be used, which comprises a transmitter means arranged for effecting a change of ambient temperature (a power dissipating resister) and comprises a receiver means arranged for detecting the change of ambient temperature (an NTC resister or a semiconductor element). In an advantageous embodiment transmitter means and receiver means are used in integrated form deposited each on either side of a substrate.
